Application filed May 4, 1914. Serial No. 836,350.

To all 'whom it may concern:

Be it known that I, FRANKLIN MARSH, a citizen of the United States, andresident of Milwaukee, in the county of Milwaukee and State ofW'isconsin, have invented certain new and useful Improvements inWindows; and l do hereby declare that the following is a full, clear,and eXact description thereof.

My invention has for its object to p rovide a window capable ofresisting climatic conditions, whereby it will notV be blurred throughthe accumulation of moisture or frost thereon, the inventionbeing'particularly adapted for use in locomotive cabs, pilot houses,street cars, show windows, or wherever it is desirable to maintain aclear view.

In the arrangement and construction of my device I provide a sash havinga single pane of glass therein, to which sash is detachably secured anapertured circulating pipe, the apertures being staggered with relationto each other, whereby jets of heated compressed yair are dischargedacross the surface of the glass to thus evaporate moisture depositedthereon.

' The invention also contemplates providing means for securing thecirculating pipe and single pane of glass in their relative positionsupon the sash-frame, and to provide means whereby the sash is hinged,one of the hinge members being utilized as a coupling connection,whereby the air is delivered to the circulating pipe.

With the above objects in view the invention consists in certainpeculiarities of construction and combination of parts as hereinafterset forth with reference to the accompanying drawings and subsequentlyclaimed.

In the drawings Figure 1 represents a sectional end elevation of alocomotive cab having a window therein embodying the features of myinvention; Fig. 2, a detailed cross-section of the window, the sectionbeing indicated by line 2--2 of Fig. 1; Fig. 3, a fragmentary elevationof my preferred form ofl window construction with arts broken away andparts in section to illustrate certain structural features, and Fig. 4,an enlarged detailed cross-section of my preferred form of windowconstruction, the section being indicated by line 4-4 of Fig. 3.

Referring by characters to the drawings, 1 represents a valve-controlledm-pipe for supplying heat to a drum 2, which drum is provided with avent-cock 2', whereby the drum may be relieved of condensation. The drumencircles a coil of pipe 3, the feed end 3 of which coil of pipe extendsthrough a stuffing-box at one end of the drum and the discharge end 3extends through a stuingbox in the opposite end of said drum, as shown,it being understood that the feed end of this air pipe is connected to asuitable source of air under pressure. The righthand side of the cab isshown as having a window sash 4 hinged thereto, which sash is providedwith a standard pane of glass 5. Secured to the stiles of the sash byclamps 6 are pipe sections 7 having discharge apertures 8 that arestaggered with relation to each other. The upper and lower ends'of theseipe sections are connected by crosspipes 7, respectively, the cross-pipe7 being, in turn,` connected to the discharge end 3 of the' air supplypipe or coil 3 by a valve-controlled pipe section 9. By this arrangementit will be observed that as the air passes through the coils within theheated drum, that said air is tempered to the proper degree andthereafter is discharged into the apertured pipe sections 7 7, fromwhich the air jets are directed upon the face of the pane of glass, thesaid jets being staggered with relation to each other, whereby the fullarea of the glass is subjected to the heat influence, to thus preventthe same from clouding u by frost or moisture.

Re erring to Figs. 3 and 4 showing the preferred construction, thesash-frame 4l is channeled out to receive the pane of glass 5', theedges of which pane are arranged to seat against a rubber or leathergasket strip 10. The glass is held in itsl position within the frame andagainst the gasket by means of pairs of lugs 11 having rubber buttons 11that abut the adjacent face of the glass. These lugs 11 are aperturedfor the reception of the threaded shan-ks 12 of bolts having hooked ends12', the said Shanks being passed through apertures with which thesash-frame members are provided. rlhe hook-ends of these bolts serve asclamping members for vertically disposed apertured discharge pipesections 13, one of which sections only is shown. These sections areconnected at the top and bottom of the sashframe by cross-pipes 13',13". The upper cross-pipe 13" is provided with a downturned taperednozzle-end 14, which end is fitted into a hollow hinge bracket 15, Thisbracket 15 has tapped therein an air feedpipe 9', whereby air isdelivered to the circulating pipes about the window-pane,vthe saidnozzle 11 constituting a hinge-pintle. The cross-pipes 13', 13, in thisinstance are also apertured, whereby the transverse jets of air from thepipes 13 are intersected by longitudinal jets discharged from theapertures in the cross-pipes. The lower crosspipe 13 and onelongitudinal pipe stretch are connected at one corner by a couplingmember 16, which member has extending therefrom a pintle '17that is inaxial alinement with the discharge nozzle 14 and is adapted to be seatedin ahinge lug 17', the said hinge lug and bracket 15 being secured tothe wall ofthe cab member. By this construction the window may be swungopen without disconnecting the air supply and furthermore should a paneof glass be broken a substitute can readily 'be inserted by simplydisconnecting the clamping lugs 11 from the Shanks of the bolts 12,which shanks are provided with threaded ends for the reception of nuts12, whereby the lugs and pipe members are all securely gripped to thesash, it being understood that when the nuts 12 are removed theapertured pipes 13 are also disconnected from the sash, thisconstruction being both effective and economical from a manufacturersstandpoint.

I claim:

In a window for the purpose described having a casing, a glass tted toone face of the casing, and a fluid pipe fitted about the opposite faceof said casing; the combination of a combined attaching means for thepipe and glass comprising apertured lugs for engagement with the edgesof the glass, bolts fitted through the lug apertures and casing havinghooked ends for engagement with the pipe, and clamping nuts for thebolts engageable with the lugs.

In testimony that I claim the foregoing I have hereunto set my hand atMilwaukee in ythe county of Milwaukee and State of Wisconsin in thepresence of two witnesses.

i FRANKLIN MARSH.
